In the same part of the film, you may have also noticed the Genie pulls a crab from a cookbook. That's not just any crab, though. That's Sebastian from "The Little Mermaid." The 1991 movie was also directed by the filmmakers of "Aladdin," Ron Clements and John Musker.

During Aladdin's magic carpet ride, you can see the temple of Zeus, in the background at one point from "Hercules." At the time, this was several years before "Hercules" came out.

Fun fact: Years later, in 1999, the two had a crossover episode in a "Hercules" animated television series called "Hercules and the Arabian Nights."

Genie's outfit at the end of the movie — a Hawaiian shirt and Goofy hat — is an homage to a short, live-action and animated movie, "Back to Neverland." According to Disney, the short played for guests at Disney Animation Studio in Walt Disney World.
